Iterlim

This option specifies the maximum number of allowable solver iterations, before the solver terminates the run.  This option is used by setting

Option Iterlim=number;

As of version 23.1 the default iteration limit has been increased from 10000 to 2e9. Setting IterLim to INF will not work since it is treated as an integer by GAMS and many solvers. Some solver, e.g. GAMS/Gurobi, recognize 2e9 and set the solver iteration limit to infinity.
